CYCLOMETER.

SPEGEFIGATION forming part of Letters Patent N 0. 677,237, dated June 25, 1901. Application filed February 26, 1960. S rial No. 6,460. (No model.)

To all whom it may concern.-

Be it known that I, JAMES A. KEYES, a citizen of the United States of America, and a resident of NewYork, county of New York, State of New York, (whose post-office address is No. 656 Hudson street, New York, N. Y.,) have invented certain new and useful Improvements in Cyclometers,(0ase A,) of which the following is a specification.

My invention relates generally to cyclometers, and is capable of use for all purposes for which such devices are ordinarily employed. In the present embodiment, however, the cyclometer is especially designed with a view to adapting it for use in connection with the larger class of vehiclest'. c. those drawn by horses or power-driven and in which one axle and the wheels thereon, together with the body-supporting springs, are in fixed relation.

The novelty of the invention lies in the mannor of mounting the cyclometer to permit of its being locked in operative position against removal by an unauthorized person, it at the same time being readily detachable for re pair, examination, &c., by proper authority;

Furthermore, the invention possesses novelty in the mechanism employed for transmitting motion from the vehicle-wheel positively, and when rotating in either direction to the registering device to cause the latter to respond by totalizing and indicating the entire distance traveled, and finally the invention embraces various main and subcombinations of parts to be hereinafterv fully described and claimed.

The invention in its preferred form is illustrated in the accompanying drawings, throughout the several views ofwhich like reference-numerals indicate corresponding parts.

, Referring to the drawings, Figure 1 is a view in elevation of an electrically-driven vehicle known as an automobile, showing the cyclometer applied thereto, one of the forward wheels being removed to more clearly illustrate the relative arrangement of parts.

' Fig. 2 is an enlarged view in detail illustrating the manner of mounting the cyclometer upon the axle of the vehicle. Fig. 3 is a view showing the cyclometer mechanism in elevation and the upper cap or casing thereof in section. Fig. 4 is a view in perspective of the detachable base and the upper portion of the cap or casing.

I Fig. 5 is a sectional view taken on the line :0 {r of Fig. 3 and showing casing. Fig. 6 is a similar view taken on the line 117 m of Fig. 3. Fig. 7 is a view in diagram illustrating the operation of the doubleacting cam and relation of other parts of the gearing which connects the ratchet-feed with the vehicle.

In the drawings,1 represents a power-driven vehicle of the class known as automobiles. 2 represents the fixed axle, and 3 the wheels thereon. 4 represents an eccentric mounted upon the hub 5 of the wheel and keyed to rotate therewith. 6 represents one of the vehicle-springs arranged in fixed relation to the axle and through the medium of which the body is connected to and supported from the running-gear, the fastenings employed for the springs being the well-known form of clipbolt 7.

8 represents a base-plate to which the cyclometer is detachably secured, and this is the preferred construction, although so far as the location and mode of securing to the the cyclometer removed from its base and vehicle are concerned the attachment of the base may be varied, if desired. This plate is provided at opposite ends with lugs 9 9 of a form suitable for taking under the clip-bolts,

above referred to, by which they are clamped,

and thus secured the base becomes practically a fixture and serves at all times to provide a seat for mounting acyclometer.

10 represents the cyclometer which comprises a registering mechanism 11, a ratchetfeed device 12, and gearing 13, connecting the feed with the vehicle-wheel.

This register 11 may be ,of any suitable or well-known form and employ any number of indicating drums or wheels 11. In the present instance, however, three wheels are shown loosely mounted upon a through-shaft 14. The wheel to the right is peripherally marked at four equispaced points with g, l, 1%, and 2 anddesigned to register half miles. The central or intermediate wheel is peripherally marked from 1 to 10, inclusive, and serves to register units- 11. e., miles. The wheel to .the left of the series is also marked from 1 to 10, inclusive, and registers tens. The ad oining edges of the rims of these wheels'are suitably notched or toothed, and through coinciding notches are operatively connected by transfergearing in a well-known manner to in- I to rotate with the register-wheel to the right i of the series. The ratchet is advanced step by step through a pawl 12, carried by a rocker arm 12, which latter is mounted loosely upon the shaft 15, carrying the trans- E The feed-pawl fer-gearing of the register. is sustained in operative relation to the ratchet ,bya spring 12 and back play'of theratchet 'i's'pre'vented by the locking-pawl 12 j Ihe rocker-arm is osci'liated by a cam 12?,

- mounted upon shaft 14 and acting upon a advance the ratchet. The 'cam consists of? anapproximaitelgy *V- shaped projection from shaft 13*, which provides amine-lined face 13 for engagement with the arm 18. Upon the outer end of the cam-shaft =a crank-arm 1'3" is'fix'ed and is provided with a stud .or anti-j friction-roil'ler'lfli,whichflatter is engaged by I the eccentricor' cam 4 upon the "h db 5 'o'f'the fixed stud 'or projection 12 thereof, and is retracted 'by means of a sp'rin'g 1'2 acting against aproj-ecting heel 1-2 'thereoi,as is i closed bya casing 24, whichis detach-abl'ysebest shown in Fig. "5.

The gearing connecting the ratchet-feed with the vehicle comprises the worm-gear. 13*,fwh'ichis loose on shaft '14 and is keyed or otherwise secured to'cam 12f, so that the gearand cam rotate together. The gear 13: meshes with and is driven by-a 'worm 13",; fixed'on and rotating "with shaft 13, whi'ch l'atterhas also mounted upon its outer end :a Q ratchet 13 Fig. '7. "This ratchet is advanced E bytasgringapressed fpawl 1 3, carried by -a'n1 7, which isfpivotedat 1'3' -'and'sustained normally in =a' retracted position by a spring Eack play of the ratchet is prevented by a spring-pressed 'locking pawl 13?, which engages continuously and ii mi-ts its m'ovement to rotation in one-direction. The arm 13 is elevated againstthe action of its spring by a single flint-earn T3 to cause the dog tog arm 1 vehicle-wheel.

"The *eccen tric orca'm '4 is secured about or 1 'tothe i nnerportion-ioft'he hub of the w-heeli-n I any convenient amann'er'and is of the inside- 1 cam' typa'lieing provided with na-conti'rruous groojve adapted to receive "the roller 'l3 'o'f the 5' crank-farm 13 v as indicated "in Figs. "1 2,?lfl1d 7, and to positively *move the arm during its revolution in "whichever waythe vehicle is? traveling, the roller 13 *folljo wing i ts ipathfin the cam 'during' either the forwardior bakJ a e r the "vehicle.

Referring to Fig. 7, the crank-armisshown j in its normal 'position. Whcnthe vehicleis traveling'ertherforward or-rearwardythe arm oscillatesiin the arc X between points cow,

Thismovement of the *cran'k arm is effected sass? by the action of the eccentric above referred to.

Themechanism of the cyclometer is mounted upon a plate 16, from which a series of uprights 17 17 17 rise to provide bearings for 1 the several shafts mentioned. This plate conforms substantially in outline to the upper surface of the. detachable base and is provided with a curved lug 18, which enters an inclined socket or opening 19 of the base "aha forms a hinge connection which is detachable only when the fastening at the opposite end of the plate is disengaged. This fastening com prises an'integral staple 20, pro

jecting from the base and upward through an opening 21, formed in the plate, which latter is secured, preferably, by a padlock orj-bolt engaging the staple.

22 represents a platewhich is 'a-pertured at 23 to expose in a line one number-of each disk. 7 V

vThe entire cyc'lometer mechanism -is"i-r1-- cured to the plate 16 and is provided with a closing cover 27, which on being swung back in opposition to the spring givesaccess-to the sight-openin g, through which the distancein dicated bythe register is exposed and may be read. I

The'operation "is as follows: The base'being in position the cyelometer is connected therewith by first entering the curved lug in the inclined opening 19 of the base i and then swinging the plate about the joint thus formed 'as 'a pivot until itrestsupo-n the base, with the staple projecting th-rough the aperturethereof. Assuming that the casing is properlysecu redto inclose the mechanism, itonly remains to place the look in position toengagethestaple. Thus secured on the forward or :rearWa-rdtraveiof the vehicle the cran'k-armwill he oscillated and through the cam mot'ion wi llbe-transmitted to the-springretracted'pawl-carryinga-rm ca-using the pawl.

It will be 'understoodthat I do not wish to limit j-myself to the exact construction -and-relat-ion o'fparts, as -herei'n illustrateda-nddescribed, as various changes might be made in the details {or the general arrangement, or mechanical-equivalents'mightbesubstituted 'for one ormore parts "hereemploy'ed, and in adapting such equivalents-Tor use in connection with the present mechanism more or less rearrangement or reconstruction may be required; but I consider all such changes as immaterial modifications and entirely within the scope of my invention.

Having therefore described the invention, I claim- 1. In a vehicle, the combination with a nonrotating axle thereof, the wheel thereon, said wheel being provided with an engaging projection, of a eyclometer supporting base mounted upon the axle, clip-bolts engaging the cyclometer-base and axle, and securing them permanently together, and the cyclometer attachable and detachable from the supporting-base and operatively arranged with said wheel projection by attachment to said base. I

2. Ina vehicle, the combination with a nonrotating axle and a casing adapted to contain a cyclometer mechanism, of a base or support therefor,projections extending from the lower part of said casingoand adapted to engage the said base to detachably secure the casing thereto, and a pair of lugs extending from thelower part of the base and adapted to be engaged by clip-bolts whereby it is permanently secured in position upon the. axle.

3, In a vehicle, thecombination with a nonrotating axle, clip-bolts engaging the axle, a

base-plate adapted to be also engaged by said I clip-bolts and thereby permanently secured upon the axle, and a cyclometer-casing registering with the upper face of the base-plate and provided with integral means adapted to connect the cyclometer and base in adjusted relation, and when engaged therewith to be in desired operative position and detachable therefrom. v

4. The combination with the axle of a vehicle and clip-bolts upon the same, of a base plate having extended parts engaged and secured in position by said clip-bolts upon the axle and having a recess at one end and a staple at the other,a cyclometer-casing formed with a lug at one endadapted to register with the recess in the upper part of the base and a slotted lug extending from vthe casing and adapted to pass over the staple as the casing is adjusted into operative position upon the base, and means for securing the casing detachably in position.
